UnifiedSessionsManager is a unified and simplified interface for the use and management of local and remote sessions on physical and virtual machines. It provides management of distributed and stacked virtual machines, management of desktops and workspaces on multiple monitors, seamless access to all types of sessions, and support of encrypted connections using SSH.
slkvm is an application to provide some system tools to work with clustering and virtualization. It focuses on depending on as few external tools as possible but to also support as many virtualization technologies as possible. It works in a cluster environment where heartbeat runs virtual machines of nodes that have failed. It builds an "unheaded" cluster to avoid having a clear point of failure. It is able to build a two node cluster with everything redundant. It avoids compiling a new kernel or newer version of applications, so you can benefit from Debian security updates.
WebVirtMgr is a libvirt-based Web interface for managing virtual machines. It allows you to create and configure new domains, and adjust a domain's resource allocation. A VNC viewer over a SSH tunnel presents a full graphical console to the guest domain. KVM is currently the only hypervisor supported.
Collax V-Family is a management suite based on a 64bit Linux system and KVM to provide server virtualization. It offers solutions for single virtualization hosts, as well as high availability management on two or more nodes, allowing embedded HA storage using DRBD and iSCSI. By using live snapshots, automatic live migration, and incremental backups, the availability of virtual machines is increased tremendously in case of hardware and software maintenance or even hardware failures. Virtual network switches and the protocols GVRP, LLDP, and RSTP help to set up a virtual DMZ.
Q-Tubes is a Web-based QEMU/KVM machine manager in Python built around the Pyramid Web framework. Its goal is to allow management of QEMU/KVM networks across single host instances, and ultimately across server farms. It supports minimal VM instances with disk support and basic network configuration (no user-space network yet), and basic VDE switch configurations. It provides a WSGI interface for deployment behind WSGI-aware servers, or provides its own basic server (python-waitress) for simple instances. The application is under steady development and has a moderate number of (Python) dependencies. Installation in a virtualenv is strongly recommended. It requires QEMU/KVM, VDE, and Python 2.7 or later.
